Patented Aug. ll, limit.

Application filed August 26, 1914:. Serial No. 858,693.

To all whom it may concern:

Be it known that I, ANDREW STRAND, a citizen of the United States of America, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Oiling Systems for Gasolene-Engines, of which the following is a specification.

My invention relates to certain new and useful improvements in oiling systems for gasolene engines and has for its object the provision of an improved methodof supplying oil to the interior of an engine cyl-' inder and consists essentially of an annular oil chamber formed in the wall of the cylinder and provided with anumber of small openings connecting said chamber with the interior of the cylinder. Oil is fed to the chamber by an improved means such as a pump as is fully shown by the accompanying drawings in which:

I Figure 1 is a sectional view showing my oiling system as applied; and Fig. 2 is a similar view of a modification thereof.

Throughout the specification and drawings in which like reference characters denote like parts, 10 denotes the. cylinder of a gas engine of either the water or air cooled type. In the wall 11 of the cylinder an annular chamber 12 is formed communicating with the interior of the cylinder by means of the small openings 13. These openings preferably open into the cylinder at a point below the top of the lowermost position of the top of the piston. By placing the openings at this level prevent the force of the explosion from entering the chamber and forcing the oil back through the pipe 15 by which it is admitted. Suitablemeans for feeding the oil to the chamber through the pipe such as an oil pump (not shown) may be supplied, the oil preferably being fed under pressure. In the alnately and oppositely inclined radial open ings disposed in staggered relation to each other and formed in the cylinderwall, of means for feeding oil to said cylinder through said openings under pressure.

p In testimony whereof afix my signature in presence of two witnesses.

ANDREW STRAND.
